Abstract

New N-pyrrolyl-3-pyridazine-amines having a further aminic substituent in the 6 position of the formula (I), <CHEM> wherein R, R1, R2 and R3 are hydrogen or lower alkyl, R4 is e.g. hydrogen or lower alkyl, R5 and R6 are e.g. lower alkyl or taken together with the adjacent nitrogen atom represent a saturated 5 - 6 membered heterocyclic ring which may contain a further heteroatom, R7 and R8 represent hydrogen or, taken together, a 1,3-butadienylene radical forming a benzo system fused with the pyridazine ring, for example N-2,5-dimethyl-1H-pyrrol-1-yl)- 6-morpholino-3-pyridazineamine or N-(2,5-dimethyl-1H-pyrrol- 1-yl)-4-(4-hydroxypiperidino)-1-phthalazineamine, and their pharmaceutically acceptable salts are made e.g. by contacting a hydrazino derivate of the formula (II), wherein the substituents have the same meaning as above or an acid addition salt thereof with a dicarbonyl compound of the formula (III), wherein the substituents have the same meaning as above, or a functional derivative thereof in the presence of an acid catalyst at a temperature between 15 DEG C and 120 DEG C. The new compounds can be used as antihypertensive agents.
